摘　　要：为有效去除水体中的四环素污染物,本研究选用光催化技术并成功制备了富氧缺陷氧化锌纳米棒作为光催化剂。通过改变制备条件,可以调控氧化锌晶体中的氧缺陷含量及组分,并进一步影响材料的光催化性能。制备的催化剂具有优秀的四环素去除及矿化性能,同时也证实了氧缺陷、氧空位以及单电子氧空位含量的提升对于光催化降解的正面作用。In order to effectively remove tetracycline pollutants in the water, this study selected photocatalytic technology and successfully prepared oxygen-enriched defect zinc oxide nanorods as photocatalysts. By changing the preparation conditions, the oxygen defect content and composition in the zinc oxide crystals could be adjusted, and the photocatalytic performance of the material could be further affected. The as-prepared catalyst revealed excellent tetracycline removal and mineralization performance, and it also confirmed the positive effect of the increase in oxygen defects, oxygen vacancies and single-electron oxygen vacancies on photocatalytic degradation.
